This part of this European Standard specifies technical delivery conditions for hot-finished seamless, electric welded and submerged arc welded steel structural hollow sections of circular, square, rectangular or elliptical forms. It applies to hollow sections formed hot, with or without subsequent heat treatment, or formed cold with subsequent heat treatment above 580 °C to obtain equivalent mechanical conditions to those obtained in the hot formed product. The general conditions (product characteristics, test methods and performance criteria that apply under the Construction Products Regulations) are specified in prEN 10210-1 and the requirements for tolerances, dimensions and sectional properties in prEN 10210-3. NOTE 1 prEN 10210-1 covers provision of the Construction Products Regulations (CPR) to fulfil European law for construction products. The technical delivery conditions are described within prEN 10210-2 in combination with Clauses 2, 3, 4, 5, 7 and 8 of prEN 10210-1. NOTE 2
